Along with IoT and AI, business development utilizing blockchain is becoming more widespread. At the same time, because blockchain is a new technological field, many people are also concerned about how best to ensure its security.

In fact, while blockchain has benefits, including making tampering difficult, there is another side to it, where security must be taken into consideration based on standpoints different from those of conventional systems.

We therefore provide our Blockchain Assessment service in order to improve security when customers develop businesses based on blockchain technology.

Blockchain Technologies

Blockchain consists of various technical elements, and security standpoints differ for each element.

Smart Contracts

Blockchain Platform Connection

DApps and Proprietary Apps

Blockchain Platform Settings (Consortium-type)

In the Blockchain Assessment, multiple security assessments are performed, including evaluations and recommendations, for each element.

Security for Smart Contracts

Smart contracts is common technology in the blockchain system. It also means smart contracts are always facing danger from attackers. If vulnerabilities exist in a smart contract, it would cause a risk of illegal manipulation of transactions. In addition, smart contracts cannot be modified once they are released to blockchain. It is critical to develop smart contract securely before the releasing it to blockchain platform.

Security practices for smart contracts differ from the secure coding practices applied to conventional web and smartphone apps. Our Blockchain Assessment is based on our proprietary security criteria to check if smart contracts have vulnerabilities inside.

Smart Contract Assessments

This service combines static (main) and dynamic (secondary) analyses of smart contract source code. We use static analyses as triggers to detect issues and perform checks via dynamic analyses on our private net for a high-accuracy assessment. Expert blockchain and smart contract pentesters with GSSP certification, a qualification certifying GIAC-certified secure software programmers, are engaged in this service.

Proprietary Security Criteria

Smart contract assessment is performed based on our own security criteria. This criteria was created by integrating smart contract security practices all over the world. This criteria enables this service to reveal unique vulnerabilities which is inherent in smart contract technology. In addition, this service detect general security flaws as well, such as a buffer overflow.

Wide Coverage

Clients can use the NRI Secure Blockchain Assessment Service accross multiple different blockchain platforms and programming languages including:
